<p>
 This widget is considered too specialized/little-used for
 GTK+, and will in the future be moved to some other package.  If
 your application needs this widget, feel free to use it, as the
 widget does work and is useful in some applications; it's just not
 of general interest. However, we are not accepting new features for
 the widget, and it will eventually move out of the GTK+
 distribution.

<p>
The <a class="link" href="GtkGammaCurve.html" title="GtkGammaCurve"><span class="type">GtkGammaCurve</span></a> widget is a variant of <a class="link" href="GtkCurve.html" title="GtkCurve"><span class="type">GtkCurve</span></a> specifically for
editing gamma curves, which are used in graphics applications such as the
Gimp.
</p>
<p>
The <a class="link" href="GtkGammaCurve.html" title="GtkGammaCurve"><span class="type">GtkGammaCurve</span></a> widget shows a curve which the user can edit with the
mouse just like a <a class="link" href="GtkCurve.html" title="GtkCurve"><span class="type">GtkCurve</span></a> widget. On the right of the curve it also displays
5 buttons, 3 of which change between the 3 curve modes (spline, linear and
free), and the other 2 set the curve to a particular gamma value, or reset it
to a straight line.
